If you want that, you just run a Linux PAE kernel on 64 bit hardware. Each process runs in 32 bit task space with the kernel looking after the higher order buts in the address registers. If you have 32 bit code that you need to run, this will do it. And, if you have no need to run freshly compiled processes with multi gigabyte memory requirements, they'll run too and be a bit smaller thanks to their shorter addresses. -- martin@ | Martin Gregorie gregorie. | Essex, UK org |
